Notice and Access

We are using the “Notice and Access” system for delivery of our proxy materials to our shareholders in connection with our Annual General and Special Meeting, which is scheduled to be held virtually on Wednesday, May 6, 2026 at 10:00am. (Toronto time) (the “Meeting”).

The meeting materials, consisting of our 2026 management information circular (the “Circular”), the notice of meeting, the form of proxy and the audited consolidated financial statements for the financial year 2025 (the “2025 Financial Statements”) and the related management’s discussion and analysis (the “2025 MD&A”, and collectively, the “Meeting Materials”) have been posted here and on our profile on SEDAR+ at www.sedarplus.ca (in lieu of mailing the Meeting Materials to our shareholders).

Notice and Access is an environmentally friendly and cost-effective way to distribute these Meeting Materials since it reduces printing, paper and postage.

In an effort to make the Meeting more accessible to our shareholders, the Meeting will be held virtual only via live webcast at https://meetings.lumiconnect.com/400-890-200-229 (password: altus2026).
